-.. title:: AbstractMiddleware
-
-AbstractMiddleware
-##################
-
-.. sidebar:: Table of Contents
-  .. contents::
-
-The `AbstractMiddleware` is a little helper for creating your own middlewares. It processes the incoming request before
-handing it over to the next middleware in line, and later processes the response before returning it to the previous
-middleware. Originally both methods just return their argument unchanged, so you should implement either one of them or
-both as needed.
-
-The `AbstractMiddleware` implements the `Psr\Http\Server\MiddlewareInterface` following PHP-FIG's recommendation
-`PSR-15: HTTP Server Request Handlers <https://www.php-fig.org/psr/psr-15/>`_.
-
-Properties
-==========
-
-The `AbstractMiddleware` has a single protected property `AbstractMiddleware::requestHandler` referencing the request
-handler which called the middleware. This can be used to access the request and/or response object (as properties of
-:doc:`queuerequesthandler`) when they are otherwise not available.
-
-Methods
-=======
-
-The `AbstractMiddleware` provides one public API method and two protected methods. While the former is final and makes
-sure it implements the `Psr\Http\Server\MiddlewareInterface`, the latter are intended to be extended in your own class.
-
-The main :php:method:`OCC\PSR15\AbstractMiddleware::process()` method implements the interface and is also called when
-invoking the middleware object directly. It first passes the incoming request to the
-:php:method:`OCC\PSR15\AbstractMiddleware::processRequest()` method, then hands over the result to the request handler
-to receive a response, which is then processed by :php:method:`OCC\PSR15\AbstractMiddleware::processResponse()` before
-returning it back to the request handler again.
-
-Processing a Request
---------------------
-
-The default method of `AbstractMiddleware` just returns the request unchanged. If you need to process the request, you
-have to implement your own `processRequest()` method. It takes a request object as only argument and must return a
-valid request object as well. Just make sure it follows PHP-FIG's standard recommendation
-`PSR-7: HTTP Message Interfaces <https://www.php-fig.org/psr/psr-7/>`_ and implements the
-`Psr\Http\Message\ServerRequestInterface`.
-
-Processing a Response
----------------------
-
-The default method of `AbstractMiddleware` just returns the response unchanged. If you need to process the response,
-you have to implement your own `processResponse()` method. It takes a response object as only argument and must return
-a valid response object as well. Just make sure it follows PHP-FIG's standard recommendation
-`PSR-7: HTTP Message Interfaces <https://www.php-fig.org/psr/psr-7/>`_ and implements the
-`Psr\Http\Message\ResponseInterface`.

-Overview
-########
-
-The package contains an implementation of `PSR-15: HTTP Server Request Handlers <https://www.php-fig.org/psr/psr-15/>`_
-in a queue-based variant. A :doc:`queuerequesthandler` handles an incoming HTTP request by passing it through a queue
-of one or more middlewares. The :doc:`middlewarequeue` provides the middlewares in first-in, first-out (FIFO) order,
-i.e. the HTTP request is passed from middleware to middleware preserving the order in which the middlewares were added
-to the queue. An :doc:`abstractmiddleware` helps developing your own middlewares, but you can also use any middleware
-implementing the `Psr\Http\Server\MiddlewareInterface <https://packagist.org/packages/psr/http-server-middleware>`_.
-
-All files share the highest coding standards of `PHPStan <https://phpstan.org/>`_ and `Psalm <https://psalm.dev/>`_,
-and full `PSR-12 <https://www.php-fig.org/psr/psr-12/>`_ compliance to make sure they can be combined and easily used
-in other projects.

-###############

-.. sidebar:: Table of Contents
-  .. contents::
-
-The `MiddlewareQueue` manages the middlewares involved in processing a server request. It makes sure they are called in
-first-in, first-out (FIFO) order, i.e. the same order they were added to the queue. It also ensures all middlewares are
-implementing the `PSR-15: HTTP Server Request Handlers <https://www.php-fig.org/psr/psr-15/>`_ specification for the
-`Psr\Http\Server\MiddlewareInterface`.
-
-When instantiating a `MiddlewareQueue` it defaults to being empty. But you can optionally pass an iterable set of
-middlewares to the constructor which are then put into the queue. To demonstrate, the following examples both have
-exactly the same result.
-
-  Examples:
-
-  .. code-block:: php
-    use OCC\PSR15\MiddlewareQueue;
-
-    $middlewares = [
-        new MiddlewareOne(),
-        new MiddlewareTwo()
-    ];
-
-    $queue = new MiddlewareQueue($middlewares);
-
-  .. code-block:: php
-    use OCC\PSR15\MiddlewareQueue;
-
-    $queue = new MiddlewareQueue();
-
-    $queue->enqueue(new MiddlewareOne());
-    $queue->enqueue(new MiddlewareTwo());
-
-The `MiddlewareQueue` is based on a `OCC\Basics\DataStructures\StrictQueue`.
-
-Methods
-=======
-
-The `MiddlewareQueue` provides a set of API methods, with `MiddlewareQueue::enqueue()` and `MiddlewareQueue::dequeue()`
-being the most relevant ones. The former will add a new item at the end of the queue while the latter removes and
-returns the first item from the queue.
-
-For a complete API documentation have a look at the
-`StrictQueue <https://opencultureconsulting.github.io/php-basics/classes/OCC-Basics-DataStructures-StrictQueue.html>`_.
-
-Adding a Middleware
--------------------
-
-Invoking `MiddlewareQueue::enqueue()` will add a middleware at the end of the queue. The only argument must be a
-middleware object implementing the `Psr\Http\Server\MiddlewareInterface`. If the given argument does not meet the
-criterion an `OCC\Basics\DataStructures\Exceptions\InvalidDataTypeException` is thrown.
-
-Have a look at the :doc:`abstractmiddleware` for an easy way to create your own middlewares!
-
-Fetching the next in line
--------------------------
-
-Calling `MiddlewareQueue::dequeue()` will return the first middleware from the queue, i.e. the oldest one on the queue.
-Also, this middleware is removed from the queue.
-
-If the queue is empty a `RuntimeException` is thrown, so make sure to check the queue's length (e.g. with `count()`)
-before trying to dequeue an item!

-QueueRequestHandler
-###################
-
-.. sidebar:: Table of Contents
-  .. contents::
-
-The `QueueRequestHandler` is the core piece of this package. It fetches incoming HTTP requests, passes them through a
-queue of middlewares and finally sends the response back to the client. It also catches any exceptions not handled by
-a middleware and turns them into a proper HTTP error response.
-
-The `QueueRequestHandler` implements the `Psr\Http\Server\RequestHandlerInterface` following PHP-FIG's recommendation
-`PSR-15: HTTP Server Request Handlers <https://www.php-fig.org/psr/psr-15/>`_.
-
-For a minimal working example have a look at :doc:`../usage/usage`.
-
-Properties
-==========
-
-The `QueueRequestHandler` has three **read-only** properties. They are initially set at instantiation and can be
-directly accessed from the object via magic methods (e.g. `$requestHandler->queue`).
-
-Middleware Queue
-----------------
-
-The queue of middlewares can be accessed as `QueueRequestHandler::queue` and offers a handy API to `enqueue()`,
-`dequeue()` or otherwise manipulate its contents. All middlewares must implement `Psr\Http\Server\MiddlewareInterface`.
-Have a look at :doc:`middlewarequeue` for more details.
-
-When instantiating a `QueueRequestHandler` the queue defaults to being empty. But you can optionally pass an iterable
-set of middlewares to the constructor which are then put into the queue. To demonstrate, the following examples both
-have exactly the same result.
-
-  Examples:
-
-  .. code-block:: php
-    use OCC\PSR15\QueueRequestHandler;
-
-    $middlewares = [
-        new MiddlewareOne(),
-        new MiddlewareTwo()
-    ];
-
-    $requestHandler = new QueueRequestHandler($middlewares);
-
-  .. code-block:: php
-    use OCC\PSR15\QueueRequestHandler;
-
-    $requestHandler = new QueueRequestHandler();
-
-    $requestHandler->queue->enqueue(new MiddlewareOne());
-    $requestHandler->queue->enqueue(new MiddlewareTwo());
-
-HTTP Server Request
--------------------
-
-The server request is always available as `QueueRequestHandler::request`. It follows PHP-FIG's standard recommendation
-`PSR-7: HTTP Message Interfaces <https://www.php-fig.org/psr/psr-7/>`_ and implements the
-`Psr\Http\Message\ServerRequestInterface`.
-
-When instantiating a `QueueRequestHandler` the `$request` property is initially set by fetching the actual server
-request data from superglobals. The property is reset each time the request is passed through a middleware and thus
-always represents the current state of the request.
-
-HTTP Response
--------------
-
-The response can be read as `QueueRequestHandler::response`. It also follows PHP-FIG's standard recommendation
-`PSR-7: HTTP Message Interfaces <https://www.php-fig.org/psr/psr-7/>`_ and implements the
-`Psr\Http\Message\ResponseInterface`.
-
-When instantiating a `QueueRequestHandler` the `$response` property is initially set as a blank HTTP response with
-status code `200`. The property is reset each time the response is passed through a middleware and thus
-always represents the latest state of the response.
-
-Both, request and response, use the awesome implementations of `Guzzle <https://github.com/guzzle/psr7>`_.
-
-Methods
-=======
-
-The `QueueRequestHandler` provides two public API methods, :php:method:`OCC\PSR15\QueueRequestHandler::handle()` and
-:php:method:`OCC\PSR15\QueueRequestHandler::respond()`. As their names suggest, the former handles the server request
-while the latter sends the response back to the client. Invoking the request handler object directly does the same as
-calling the `handle()` method.
-
-Handling a Server Request
--------------------------
-
-After adding at least one middleware to the queue, you can start handling a request by simply calling
-:php:method:`OCC\PSR15\QueueRequestHandler::handle()`. Optionally, you can pass a request object as argument, but since
-the actual server request was already fetched in the constructor and will be used by default, most of the time you
-don't need to. All request objects must implement `Psr\Http\Message\ServerRequestInterface`.
-
-The `handle()` method returns the final response after passing it through all middlewares. The response object always
-implements `Psr\Http\Message\ResponseInterface`.
-
-In case of an error the request handler catches any exception and creates a response with the exception code as status
-code (if it's within the valid range of HTTP status codes, otherwise it's set to `500 (Internal Server Error)`), and
-the exception message as body.
-
-Sending the Response
---------------------
-
-Sending the final response to the client is as easy as calling :php:method:`OCC\PSR15\QueueRequestHandler::respond()`.
-Optionally, you can provide an exit code as argument (an integer in the range `0` to `254`). If you do so, script
-execution is stopped after sending out the response and the given exit status is set. The status `0` means the request
-was handled successfully, every other status is considered an error.

-If you want to use a specific version other than the latest available for your environment, you can do so by appending
-the desired version constraint:
-
-.. code-block:: shell
-
-  # This will install the latest patch level version of 1.1 (i. e. >=1.1.0 && <1.2.0)
-  composer require "opencultureconsulting/psr15:~1.1"

-Git
-===
-
-Alternatively, you can fetch the files from `GitHub <https://github.com/opencultureconsulting/psr-15>`_ and add them to

-  # This will clone the repository state at version "1.1.0" into the "psr15" directory
-  git clone --branch=v1.1.0 https://github.com/opencultureconsulting/psr-15.git psr15
-
-Be aware that you also need to make the classes available in your application by either adding them to your autoloader
-or by including all files individually in PHP. Also don't forget to do the same for all :doc:`requirements`.

-Environment
-===========
-
-This package requires at least **PHP 8.1**.
-
-It is highly recommended to use `Composer <https://getcomposer.org/>`_ for dependency management and autoloading,
-although it is technically not strictly required for using any of these classes. But it certainly makes it a lot

-
-Dependencies
-============
-
-This package obviously depends on `psr/http-server-handler <https://packagist.org/packages/psr/http-server-handler>`_
-and `psr/http-server-middleware <https://packagist.org/packages/psr/http-server-middleware>`_ which define the standard
-`PSR-15: HTTP Server Request Handlers <https://www.php-fig.org/psr/psr-15/>`_ interfaces.
-
-It uses the `PSR-7: HTTP Message <https://www.php-fig.org/psr/psr-7/>`_ implementations for server request and response
-of the great `guzzlehttp/psr7 <https://packagist.org/packages/guzzlehttp/psr7>`_ library.

-Usage
-#####
-
-.. sidebar:: Table of Contents
-  .. contents::
-
-The following example shows a very basic *Queue-based HTTP Server Request Handler* using just two simple middlewares
-(called `MiddlewareOne` and `MiddlewareTwo`).
-
-Middlewares
-===========
-
-First of all, we need some middlewares to process our server request. Although we could use any middleware implementing
-the `Psr/Http/Server/MiddlewareInterface` (e.g. from `this great collection <https://github.com/middlewares>`_), we
-will write our own using the :doc:`../overview/abstractmiddleware` provided by this package.
-
-The abstract middleware already implements a complete middleware, but it will just pass requests through without doing
-anything. In order to have it do something, we need to implement our own :php:method:`OCC\PSR15\AbstractMiddleware::processRequest()`
-or :php:method:`OCC\PSR15\AbstractMiddleware::processResponse()` method, or both of them.
-
-The logic here is the same as with every `PSR-15: HTTP Server Request Handlers <https://www.php-fig.org/psr/psr-15/>`_
-middleware: The request gets passed through all middlewares' `processRequest()` methods in order of their addition to
-the queue, then a response is created and passed through all `processResponse()` methods, **but in reverse order**! So
-the first middleware in the queue gets the request first, but the response last.
-
-Our first middleware is very simple and just adds an attribute to the server request.
-
-.. code-block:: php
-  use OCC\PSR15\AbstractMiddleware;
-  use Psr\Http\Message\ServerRequestInterface as ServerRequest;
-
-  class MiddlewareOne extends AbstractMiddleware
-  {
-      /**
-       * Process an incoming server request before delegating to next middleware.
-       *
-       * @param ServerRequest $request The incoming server request
-       *
-       * @return ServerRequest The processed server request
-       */
-      protected function processRequest(ServerRequest $request): ServerRequest
-      {
-          // Let's just add a new attribute to the request to later check
-          // which middleware was passed last.
-          return $request->withAttribute('LastMiddlewarePassed', 'MiddlewareOne');
-      }
-  }
-
-For a queue to make sense we need at least a second middleware, so let's create another one. Again, we will add an
-attribute to the request, but with the same name. So, whichever middleware handles the request last overwrites the
-attribute with its value. This way we can later check if our middlewares were passed in the correct order.
-
-.. code-block:: php
-  use OCC\PSR15\AbstractMiddleware;
-  use Psr\Http\Message\ServerRequestInterface as ServerRequest;
-
-  class MiddlewareTwo extends AbstractMiddleware
-  {
-      /**
-       * Process an incoming server request before delegating to next middleware.
-       *
-       * @param ServerRequest $request The incoming server request
-       *
-       * @return ServerRequest The processed server request
-       */
-      protected function processRequest(ServerRequest $request): ServerRequest
-      {
-          // We add the same request attribute as in MiddlewareOne, effectively
-          // overwriting its value.
-          return $request->withAttribute('LastMiddlewarePassed', 'MiddlewareTwo');
-      }
-  }
-
-Also, we want to set the status code of the response according to the final value of our request attribute. Therefore,
-we need to implement `processResponse()` as well. We can do that in either one of our middlewares because it's the only
-response manipulation in our example, so the order of processing doesn't make a difference (remember: `MiddlewareTwo`
-gets to handle the response before `MiddlewareOne`). Let's go with `MiddlewareTwo`.
-
-.. code-block:: php
-  use OCC\PSR15\AbstractMiddleware;
-  use Psr\Http\Message\ResponseInterface as Response;
-  use Psr\Http\Message\ServerRequestInterface as ServerRequest;
-
-  class MiddlewareTwo extends AbstractMiddleware
-  {
-      // MiddlewareTwo::processRequest() remains unchanged (see above).
-
-      /**
-       * Process an incoming response before returning it to previous middleware.
-       *
-       * @param Response $response The incoming response
-       *
-       * @return Response The processed response
-       */
-      protected function processResponse(Response $response): Response
-      {
-          // First we need to get the request attribute.
-          $lastMiddlewarePassed = $this->requestHandler->request->getAttribute('LastMiddlewarePassed');
-          if ($lastMiddlewarePassed === 'MiddlewareTwo') {
-              // Great, MiddlewareTwo was passed after MiddlewareOne,
-              // let's return status code 200!
-              return $response->withStatus(200);
-          } else {
-              // Oh no, something went wrong! We'll send status code 500.
-              return $response->withStatus(500);
-          }
-      }
-  }
-
-Well done! We now have two middlewares.
-
-Request Handler
-===============
-
-Let's use a :doc:`../overview/queuerequesthandler` to pass a server request through both of our middlewares in the
-correct order.
-
-.. code-block:: php
-  use OCC\PSR15\QueueRequestHandler;
-
-  // First of all, we instantiate the request handler.
-  // At this point we could already provide an array of middlewares as argument and
-  // skip the next step, but then we wouldn't learn how to use the MiddlewareQueue.
-  $requestHandler = new QueueRequestHandler();
-
-  // We can access the MiddlewareQueue as a property of the request handler.
-  // Let's add both of our middlewares, MiddlewareOne and MiddlewareTwo. Since
-  // this is a FIFO queue, the order is very important!
-  $requestHandler->queue->enqueue(new MiddlewareOne());
-  $requestHandler->queue->enqueue(new MiddlewareTwo());
-
-  // And we are ready to handle incoming requests!
-  // We don't even need to pass the server request to this method, because
-  // the constructor already took care of that!
-  $finalResponse = $requestHandler->handle();
-
-  // Now we can pass the final response back to our application.
-  // Alternatively, we can also return it directly to the client.
-  $requestHandler->respond();
-
-  // If we did everything right, the client should now receive an HTTP response
-  // with status code 200 (OK).
-
-And that's it!
-
-Diving Deeper
-=============
-
-To familiarize yourself with the FIFO principle of the middleware queue, you can try to exchange the two lines adding
-the middlewares to the queue, i.e. add `MiddlewareTwo` first and `MiddlewareOne` second. This will result in an HTTP
-response with status code `500 (Internal Server Error)`.
-
-This is exactly what we intended: Have a look at `MiddlewareTwo::processResponse()` again! If `$lastMiddlewarePassed`
-is not `MiddlewareTwo` (which it isn't when `MiddlewareOne` is added to the queue after `MiddlewareTwo`), we set the
-response status code to `500`.

 # Queue-based HTTP Server Request Handler
 
-***An implementation of [PSR-15: HTTP Server Request Handlers](https://www.php-fig.org/psr/psr-15/).***
+[![PHPStan](https://github.com/opencultureconsulting/psr-15/actions/workflows/phpstan.yml/badge.svg)](https://github.com/opencultureconsulting/psr-15/actions/workflows/phpstan.yml)
-
-The PHP Standard Recommendation PSR-15 defines interfaces for server request handlers and proposes a queue-based implementation using different middlewares for processing requests and preparing responses. This package follows those guidelines and provides a [HTTP server request handler](src/QueueRequestHandler.php) implementation using a [middleware queue](src/MiddlewareQueue.php). It also contains an [abstract class for middlewares](src/AbstractMiddleware.php) to ease the process of writing your own middleware, but you can just as well use any middleware that implements `Psr\Http\Server\MiddlewareInterface` specified by PSR-15 (e.g. from the awesome [PSR-15 HTTP Middlewares](https://github.com/middlewares) project).
-
-All components of this package follow the highest coding standards of [PHPStan](https://phpstan.org/) and [Psalm](https://psalm.dev/), and comply to [PSR-12](https://www.php-fig.org/psr/psr-12/) code style guidelines to make sure they can be combined and easily used in other projects.
-
-## Quick Start
-
-The intended and recommended way of using this package is via [Composer](https://getcomposer.org/). The following command will get you the latest version:
-
-```shell
-composer require opencultureconsulting/psr15
-```
-
-All available versions as well as further information about requirements and dependencies can be found on [Packagist](https://packagist.org/packages/opencultureconsulting/psr15).
-
-## Full Documentation

-    <p>The <code>AbstractMiddleware</code>
- is a little helper for creating your own middlewares. It processes the incoming request before
-handing it over to the next middleware in line, and later processes the response before returning it to the previous
-middleware. Originally both methods just return their argument unchanged, so you should implement either one of them or
-both as needed.</p>
-
-            
-    <p>The <code>AbstractMiddleware</code>
- implements the
-<a href="https://www.php-fig.org/psr/psr-15/#22-psrhttpservermiddlewareinterface">Psr\Http\Server\MiddlewareInterface</a>
-following PHP-FIG&#039;s recommendation <a href="https://www.php-fig.org/psr/psr-15/">PSR-15: HTTP Server Request Handlers</a>.</p>

-    <p>The <code>AbstractMiddleware</code>
- has a single protected property <code>AbstractMiddleware::requestHandler</code>
- referencing the request
-handler which called the middleware. This can be used to access the request and/or response object (as properties of
-<a href="guides/overview/queuerequesthandler.html">QueueRequestHandler</a>) when they are otherwise not available.</p>

- provides one public API method and two protected methods. While the former is final and makes

-invoking the middleware object directly. It first passes the incoming request to the
-<a href="classes/OCC-PSR15-AbstractMiddleware.html#method_processRequest"><abbr title="\OCC\PSR15\AbstractMiddleware::processRequest()">AbstractMiddleware::processRequest()</abbr></a>
- method, then hands over the result to the request handler
-to receive a response, which is then processed by <a href="classes/OCC-PSR15-AbstractMiddleware.html#method_processResponse"><abbr title="\OCC\PSR15\AbstractMiddleware::processResponse()">AbstractMiddleware::processResponse()</abbr></a>

-    <p>The package contains an implementation of <a href="https://www.php-fig.org/psr/psr-15/">PSR-15: HTTP Server Request Handlers</a>
-in a queue-based variant. A <a href="guides/overview/queuerequesthandler.html">QueueRequestHandler</a> handles an incoming HTTP request by passing it through a queue
-of one or more middlewares. The <a href="guides/overview/middlewarequeue.html">MiddlewareQueue</a> provides the middlewares in first-in, first-out (FIFO) order,
-i.e. the HTTP request is passed from middleware to middleware preserving the order in which the middlewares were added
-to the queue. An <a href="guides/overview/abstractmiddleware.html">AbstractMiddleware</a> helps developing your own middlewares, but you can also use any middleware
-implementing the <a href="https://packagist.org/packages/psr/http-server-middleware">Psr\Http\Server\MiddlewareInterface</a>.</p>
-
-            
-    <p>All files share the highest coding standards of <a href="https://phpstan.org/">PHPStan</a> and <a href="https://psalm.dev/">Psalm</a>,
-and full <a href="https://www.php-fig.org/psr/psr-12/">PSR-12</a> compliance to make sure they can be combined and easily used
-in other projects.</p>

-    <p>The <code>MiddlewareQueue</code>
- manages the middlewares involved in processing a server request. It makes sure they are called in
-first-in, first-out (FIFO) order, i.e. the same order they were added to the queue. It also ensures all middlewares are
-implementing the <a href="https://www.php-fig.org/psr/psr-15/">PSR-15: HTTP Server Request Handlers</a> specification for the
-<a href="https://www.php-fig.org/psr/psr-15/#22-psrhttpservermiddlewareinterface">Psr\Http\Server\MiddlewareInterface</a>.</p>
-
-            
-    <p>When instantiating a <code>MiddlewareQueue</code>
- it defaults to being empty. But you can optionally pass an iterable set of
-middlewares to the constructor which are then put into the queue. To demonstrate, the following examples both have
-exactly the same result.</p>
-
-            <blockquote>
-    <p>Examples:</p>
-<pre><code class="language-php">use OCC\PSR15\MiddlewareQueue;
-
-$middlewares = [
-    new MiddlewareOne(),
-    new MiddlewareTwo()
-];
-
-$queue = new MiddlewareQueue($middlewares);</code></pre>
-<pre><code class="language-php">use OCC\PSR15\MiddlewareQueue;
-
-$queue = new MiddlewareQueue();
-
-$queue-&gt;enqueue(new MiddlewareOne());
-$queue-&gt;enqueue(new MiddlewareTwo());</code></pre>
-</blockquote>
-
-            
-    <p>The <code>MiddlewareQueue</code>
- is based on a
-<a href="https://opencultureconsulting.github.io/php-basics/guides/overview/datastructures.html#strictqueue">OCC\Basics\DataStructures\StrictQueue</a>.</p>

-    <p>The <code>MiddlewareQueue</code>
- provides a set of API methods, with <code>MiddlewareQueue::enqueue()</code>
- and <code>MiddlewareQueue::dequeue()</code>
-
-being the most relevant ones. The former will add a new item at the end of the queue while the latter removes and
-returns the first item from the queue.</p>
-
-            
-    <p>For a complete API documentation have a look at the

-            <h3>Adding a Middleware</h3>
-
-            
-    <p>Invoking <code>MiddlewareQueue::enqueue()</code>
- will add a middleware at the end of the queue. The only argument must be a
-middleware object implementing the <code>Psr\Http\Server\MiddlewareInterface</code>
-. If the given argument does not meet the
-criterion an <code>OCC\Basics\DataStructures\Exceptions\InvalidDataTypeException</code>
- is thrown.</p>
-
-            
-    <p>Have a look at the <a href="guides/overview/abstractmiddleware.html">AbstractMiddleware</a> for an easy way to create your own middlewares!</p>

-            <h3>Fetching the next in line</h3>
-
-            
-    <p>Calling <code>MiddlewareQueue::dequeue()</code>
- will return the first middleware from the queue, i.e. the oldest one on the queue.
-Also, this middleware is removed from the queue.</p>
-
-            
-    <p>If the queue is empty a <code>RuntimeException</code>
- is thrown, so make sure to check the queue&#039;s length (e.g. with <code>count()</code>
-)
-before trying to dequeue an item!</p>

-    <p>The <code>QueueRequestHandler</code>
- is the core piece of this package. It fetches incoming HTTP requests, passes them through a
-queue of middlewares and finally sends the response back to the client. It also catches any exceptions not handled by
-a middleware and turns them into a proper HTTP error response.</p>
-
-            
-    <p>The <code>QueueRequestHandler</code>
- implements the
-<a href="https://www.php-fig.org/psr/psr-15/#21-psrhttpserverrequesthandlerinterface">Psr\Http\Server\RequestHandlerInterface</a>
-following PHP-FIG&#039;s recommendation <a href="https://www.php-fig.org/psr/psr-15/">PSR-15: HTTP Server Request Handlers</a>.</p>
-
-            
-    <p>For a minimal working example have a look at <a href="guides/usage/usage.html">Usage</a>.</p>
-
-            <div class="section" id="properties">
-            <h2>Properties</h2>
-
-            
-    <p>The <code>QueueRequestHandler</code>
- has three <strong>read-only</strong>
- properties. They are initially set at instantiation and can be
-directly accessed from the object via magic methods (e.g. <code>$requestHandler-&gt;queue</code>
-).</p>
-
-            <div class="section" id="middleware-queue">
-            <h3>Middleware Queue</h3>
-
-            
-    <p>The queue of middlewares can be accessed as <code>QueueRequestHandler::queue</code>
- and offers a handy API to <code>enqueue()</code>
-,
-<code>dequeue()</code>
- or otherwise manipulate its contents. All middlewares must implement <code>Psr\Http\Server\MiddlewareInterface</code>
-.
-Have a look at <a href="guides/overview/middlewarequeue.html">MiddlewareQueue</a> for more details.</p>
-
-            
-    <p>When instantiating a <code>QueueRequestHandler</code>
- the queue defaults to being empty. But you can optionally pass an iterable
-set of middlewares to the constructor which are then put into the queue. To demonstrate, the following examples both
-have exactly the same result.</p>
-
-            <blockquote>
-    <p>Examples:</p>
-<pre><code class="language-php">use OCC\PSR15\QueueRequestHandler;
-
-$middlewares = [
-    new MiddlewareOne(),
-    new MiddlewareTwo()
-];
-
-$requestHandler = new QueueRequestHandler($middlewares);</code></pre>
-<pre><code class="language-php">use OCC\PSR15\QueueRequestHandler;
-
-$requestHandler = new QueueRequestHandler();
-
-$requestHandler-&gt;queue-&gt;enqueue(new MiddlewareOne());
-$requestHandler-&gt;queue-&gt;enqueue(new MiddlewareTwo());</code></pre>
-</blockquote>
-
-    </div>
-
-            <div class="section" id="http-server-request">
-            <h3>HTTP Server Request</h3>
-
-            
-    <p>The server request is always available as <code>QueueRequestHandler::request</code>
-. It follows PHP-FIG&#039;s standard recommendation
-<a href="https://www.php-fig.org/psr/psr-7/">PSR-7: HTTP Message Interfaces</a> and implements the
-<a href="https://www.php-fig.org/psr/psr-7/#321-psrhttpmessageserverrequestinterface">Psr\Http\Message\ServerRequestInterface</a>.</p>
-
-            
-    <p>When instantiating a <code>QueueRequestHandler</code>
- the <code>$request</code>
- property is initially set by fetching the actual server
-request data from superglobals. The property is reset each time the request is passed through a middleware and thus
-always represents the current state of the request.</p>
-
-    </div>
-
-            <div class="section" id="http-response">
-            <h3>HTTP Response</h3>
-
-            
-    <p>The response can be read as <code>QueueRequestHandler::response</code>
-. It also follows PHP-FIG&#039;s standard recommendation
-<a href="https://www.php-fig.org/psr/psr-7/">PSR-7: HTTP Message Interfaces</a> and implements the
-<a href="https://www.php-fig.org/psr/psr-7/#33-psrhttpmessageresponseinterface">Psr\Http\Message\ResponseInterface</a>.</p>
-
-            
-    <p>When instantiating a <code>QueueRequestHandler</code>
- the <code>$response</code>
- property is initially set as a blank HTTP response with
-status code <code>200</code>
-. The property is reset each time the response is passed through a middleware and thus
-always represents the latest state of the response.</p>
-
-            
-    <p>Both, request and response, use the awesome implementations of <a href="https://github.com/guzzle/psr7">Guzzle</a>.</p>

-            <h2>Methods</h2>
-
-            
-    <p>The <code>QueueRequestHandler</code>
- provides two public API methods, <a href="classes/OCC-PSR15-QueueRequestHandler.html#method_handle"><abbr title="\OCC\PSR15\QueueRequestHandler::handle()">QueueRequestHandler::handle()</abbr></a>
- and
-<a href="classes/OCC-PSR15-QueueRequestHandler.html#method_respond"><abbr title="\OCC\PSR15\QueueRequestHandler::respond()">QueueRequestHandler::respond()</abbr></a>
-. As their names suggest, the former handles the server request
-while the latter sends the response back to the client. Invoking the request handler object directly does the same as
-calling the <code>handle()</code>
- method.</p>
-
-            <div class="section" id="handling-a-server-request">
-            <h3>Handling a Server Request</h3>
-
-            
-    <p>After adding at least one middleware to the queue, you can start handling a request by simply calling
-<a href="classes/OCC-PSR15-QueueRequestHandler.html#method_handle"><abbr title="\OCC\PSR15\QueueRequestHandler::handle()">QueueRequestHandler::handle()</abbr></a>
-. Optionally, you can pass a request object as argument, but since
-the actual server request was already fetched in the constructor and will be used by default, most of the time you
-don&#039;t need to. All request objects must implement <code>Psr\Http\Message\ServerRequestInterface</code>
-.</p>
-
-            
-    <p>The <code>handle()</code>
- method returns the final response after passing it through all middlewares. The response object always
-implements <code>Psr\Http\Message\ResponseInterface</code>
-.</p>
-
-            
-    <p>In case of an error the request handler catches any exception and creates a response with the exception code as status
-code (if it&#039;s within the valid range of HTTP status codes, otherwise it&#039;s set to <code>500 (Internal Server Error)</code>
-), and
-the exception message as body.</p>
-
-    </div>
-
-            <div class="section" id="sending-the-response">
-            <h3>Sending the Response</h3>
-
-            
-    <p>Sending the final response to the client is as easy as calling <a href="classes/OCC-PSR15-QueueRequestHandler.html#method_respond"><abbr title="\OCC\PSR15\QueueRequestHandler::respond()">QueueRequestHandler::respond()</abbr></a>
-.
-Optionally, you can provide an exit code as argument (an integer in the range <code>0</code>
- to <code>254</code>
-). If you do so, script
-execution is stopped after sending out the response and the given exit status is set. The status <code>0</code>
- means the request
-was handled successfully, every other status is considered an error.</p>

-    <p>The intended and recommended way of re-using this package is via <a href="https://getcomposer.org/">Composer</a>. The following
-command will get you the latest version and make it a dependency of your project. It will also request all dependencies
-and register all classes with the autoloader to make them available inside the application.</p>
-
-            <pre><code class="language-shell"># This will install the latest stable version suitable for your project
-composer require &quot;opencultureconsulting/psr15&quot;</code></pre>
-
-            
-    <p>If you want to use a specific version other than the latest available for your environment, you can do so by appending
-the desired version constraint:</p>
-
-            <pre><code class="language-shell"># This will install the latest patch level version of 1.1 (i. e. &gt;=1.1.0 &amp;&amp; &lt;1.2.0)
-composer require &quot;opencultureconsulting/psr15:~1.1&quot;</code></pre>
-
-            
-    <p>All available versions as well as further information about <a href="guides/usage/requirements.html">Requirements</a> and dependencies can be found on
-<a href="https://packagist.org/packages/opencultureconsulting/psr15">Packagist</a>.</p>
-

-
-            <div class="section" id="git">
-            <h2>Git</h2>
-
-            
-    <p>Alternatively, you can fetch the files from <a href="https://github.com/opencultureconsulting/psr-15">GitHub</a> and add them to
-your project manually. The best way is by cloning the repository, because then you can easily update to a newer version
-by just pulling the changes and checking out a different version tag.</p>
-
-            <pre><code class="language-shell"># This will clone the repository into the &quot;psr15&quot; directory
-git clone https://github.com/opencultureconsulting/psr-15.git psr15</code></pre>
-
-            
-    <p>If you want to use a specific version other than the latest development state, you have to specify the desired tag as
-well:</p>
-
-            <pre><code class="language-shell"># This will clone the repository state at version &quot;1.1.0&quot; into the &quot;psr15&quot; directory
-git clone --branch=v1.1.0 https://github.com/opencultureconsulting/psr-15.git psr15</code></pre>
-
-            
-    <p>Be aware that you also need to make the classes available in your application by either adding them to your autoloader
-or by including all files individually in PHP. Also don&#039;t forget to do the same for all <a href="guides/usage/requirements.html">Requirements</a>.</p>

-
-            <div class="section" id="download">
-            <h2>Download</h2>
-
-            
-    <p>As a last resort you can also just download the files. You can find all available versions as well as the current
-development state on the <a href="https://github.com/opencultureconsulting/psr-15/releases">GitHub release page</a>.</p>

-
-            
-    <p>It is highly recommended to use <a href="https://getcomposer.org/">Composer</a> for dependency management and autoloading,

-of the great <a href="https://packagist.org/packages/guzzlehttp/psr7">guzzlehttp/psr7</a> library.</p>
-
-            
-    <p>The middleware queue is based on a <a href="https://opencultureconsulting.github.io/php-basics/guides/overview/datastructures.html#strictqueue">StrictQueue</a>

-            
-    <p>The following example shows a very basic <em>Queue-based HTTP Server Request Handler</em>
- using just two simple middlewares
-(called <code>MiddlewareOne</code>
- and <code>MiddlewareTwo</code>
-).</p>
-
-            <div class="section" id="middlewares">
-            <h2>Middlewares</h2>
-
-            
-    <p>First of all, we need some middlewares to process our server request. Although we could use any middleware implementing
-the <code>Psr/Http/Server/MiddlewareInterface</code>
- (e.g. from <a href="https://github.com/middlewares">this great collection</a>), we
-will write our own using the <a href="guides/overview/abstractmiddleware.html">AbstractMiddleware</a> provided by this package.</p>
-
-            
-    <p>The abstract middleware already implements a complete middleware, but it will just pass requests through without doing
-anything. In order to have it do something, we need to implement our own <a href="classes/OCC-PSR15-AbstractMiddleware.html#method_processRequest"><abbr title="\OCC\PSR15\AbstractMiddleware::processRequest()">AbstractMiddleware::processRequest()</abbr></a>
-
-or <a href="classes/OCC-PSR15-AbstractMiddleware.html#method_processResponse"><abbr title="\OCC\PSR15\AbstractMiddleware::processResponse()">AbstractMiddleware::processResponse()</abbr></a>
- method, or both of them.</p>
-
-            
-    <p>The logic here is the same as with every <a href="https://www.php-fig.org/psr/psr-15/">PSR-15: HTTP Server Request Handlers</a>
-middleware: The request gets passed through all middlewares&#039; <code>processRequest()</code>
- methods in order of their addition to
-the queue, then a response is created and passed through all <code>processResponse()</code>
- methods, <strong>but in reverse order</strong>
-! So
-the first middleware in the queue gets the request first, but the response last.</p>
-
-            
-    <p>Our first middleware is very simple and just adds an attribute to the server request.</p>
-
-            <pre><code class="language-php">use OCC\PSR15\AbstractMiddleware;
-use Psr\Http\Message\ServerRequestInterface as ServerRequest;
-
-class MiddlewareOne extends AbstractMiddleware
-{
-    /**
-     * Process an incoming server request before delegating to next middleware.
-     *
-     * @param ServerRequest $request The incoming server request
-     *
-     * @return ServerRequest The processed server request
-     */
-    protected function processRequest(ServerRequest $request): ServerRequest
-    {
-        // Let&#039;s just add a new attribute to the request to later check
-        // which middleware was passed last.
-        return $request-&gt;withAttribute(&#039;LastMiddlewarePassed&#039;, &#039;MiddlewareOne&#039;);
-    }
-}</code></pre>
-
-            
-    <p>For a queue to make sense we need at least a second middleware, so let&#039;s create another one. Again, we will add an
-attribute to the request, but with the same name. So, whichever middleware handles the request last overwrites the
-attribute with its value. This way we can later check if our middlewares were passed in the correct order.</p>
-
-            <pre><code class="language-php">use OCC\PSR15\AbstractMiddleware;
-use Psr\Http\Message\ServerRequestInterface as ServerRequest;
-
-class MiddlewareTwo extends AbstractMiddleware
-{
-    /**
-     * Process an incoming server request before delegating to next middleware.
-     *
-     * @param ServerRequest $request The incoming server request
-     *
-     * @return ServerRequest The processed server request
-     */
-    protected function processRequest(ServerRequest $request): ServerRequest
-    {
-        // We add the same request attribute as in MiddlewareOne, effectively
-        // overwriting its value.
-        return $request-&gt;withAttribute(&#039;LastMiddlewarePassed&#039;, &#039;MiddlewareTwo&#039;);
-    }
-}</code></pre>
-
-            
-    <p>Also, we want to set the status code of the response according to the final value of our request attribute. Therefore,
-we need to implement <code>processResponse()</code>
- as well. We can do that in either one of our middlewares because it&#039;s the only
-response manipulation in our example, so the order of processing doesn&#039;t make a difference (remember: <code>MiddlewareTwo</code>
-
-gets to handle the response before <code>MiddlewareOne</code>
-). Let&#039;s go with <code>MiddlewareTwo</code>
-.</p>
-
-            <pre><code class="language-php">use OCC\PSR15\AbstractMiddleware;
-use Psr\Http\Message\ResponseInterface as Response;
-use Psr\Http\Message\ServerRequestInterface as ServerRequest;
-
-class MiddlewareTwo extends AbstractMiddleware
-{
-    // MiddlewareTwo::processRequest() remains unchanged (see above).
-
-    /**
-     * Process an incoming response before returning it to previous middleware.
-     *
-     * @param Response $response The incoming response
-     *
-     * @return Response The processed response
-     */
-    protected function processResponse(Response $response): Response
-    {
-        // First we need to get the request attribute.
-        $lastMiddlewarePassed = $this-&gt;requestHandler-&gt;request-&gt;getAttribute(&#039;LastMiddlewarePassed&#039;);
-        if ($lastMiddlewarePassed === &#039;MiddlewareTwo&#039;) {
-            // Great, MiddlewareTwo was passed after MiddlewareOne,
-            // let&#039;s return status code 200!
-            return $response-&gt;withStatus(200);
-        } else {
-            // Oh no, something went wrong! We&#039;ll send status code 500.
-            return $response-&gt;withStatus(500);
-        }
-    }
-}</code></pre>
-
-            
-    <p>Well done! We now have two middlewares.</p>

-            <div class="section" id="request-handler">
-            <h2>Request Handler</h2>

-            
-    <p>Let&#039;s use a <a href="guides/overview/queuerequesthandler.html">QueueRequestHandler</a> to pass a server request through both of our middlewares in the
-correct order.</p>
-
-            <pre><code class="language-php">use OCC\PSR15\QueueRequestHandler;
-
-// First of all, we instantiate the request handler.
-// At this point we could already provide an array of middlewares as argument and

-$requestHandler = new QueueRequestHandler();
-
-// We can access the MiddlewareQueue as a property of the request handler.

-            <h2>Diving Deeper</h2>
-
-            
-    <p>To familiarize yourself with the FIFO principle of the middleware queue, you can try to exchange the two lines adding
-the middlewares to the queue, i.e. add <code>MiddlewareTwo</code>
- first and <code>MiddlewareOne</code>
- second. This will result in an HTTP
-response with status code <code>500 (Internal Server Error)</code>
-.</p>
-
-            
-    <p>This is exactly what we intended: Have a look at <code>MiddlewareTwo::processResponse()</code>
- again! If <code>$lastMiddlewarePassed</code>
-
-is not <code>MiddlewareTwo</code>
- (which it isn&#039;t when <code>MiddlewareOne</code>
- is added to the queue after <code>MiddlewareTwo</code>
-), we set the
-response status code to <code>500</code>

-    Server Request Handlers</a>.</p>
-
-    <p>The PHP Standard Recommendation PSR-15 defines interfaces for server request handlers and proposes a queue-based
-    implementation using different middlewares for processing requests and preparing responses. This package follows
-    those guidelines and provides a <a href="guides/overview/queuerequesthandler.html">HTTP server request handler</a>
-    implementation using a <a href="guides/overview/middlewarequeue.html">middleware queue</a>. It also contains an
-    <a href="guides/overview/abstractmiddleware.html">abstract class for middlewares</a> to ease the process of writing
-    your own middleware, but you can just as well use any middleware that implements the middleware interface specified
-    by PSR-15 (e.g. from the awesome <a href="https://github.com/middlewares">PSR-15 HTTP Middlewares</a> project).</p>
-
-    <p>All components of this package follow the highest coding standards of <a href="https://phpstan.org/">PHPStan</a>
-    and <a href="https://psalm.dev/">Psalm</a>, and comply to <a href="https://www.php-fig.org/psr/psr-12/">PSR-12</a>
-    code style guidelines to make sure they can be combined and easily re-used in other projects.</p>

-// Search module for phpDocumentor
-//
-// This module is a wrapper around fuse.js that will use a given index and attach itself to a
-// search form and to a search results pane identified by the following data attributes:
-//
-// 1. data-search-form
-// 2. data-search-results
-//
-// The data-search-form is expected to have a single input element of type 'search' that will trigger searching for
-// a series of results, were the data-search-results pane is expected to have a direct UL child that will be populated
-// with rendered results.
-//
-// The search has various stages, upon loading this stage the data-search-form receives the CSS class
-// 'phpdocumentor-search--enabled'; this indicates that JS is allowed and indices are being loaded. It is recommended
-// to hide the form by default and show it when it receives this class to achieve progressive enhancement for this
-// feature.
-//
-// After loading this module, it is expected to load a search index asynchronously, for example:
-//
-//         <script defer src="js/searchIndex.js"></script>
-//
-// In this script the generated index should attach itself to the search module using the `appendIndex` function. By
-// doing it like this the page will continue loading, unhindered by the loading of the search.
-//
-// After the page has fully loaded, and all these deferred indexes loaded, the initialization of the search module will
-// be called and the form will receive the class 'phpdocumentor-search--active', indicating search is ready. At this
-// point, the input field will also have it's 'disabled' attribute removed.
